Nothing remarkable occurred on the journey to London. The greater part of the way there were only two gentlemen in the same compartment with me; and we occupied each our corner, with little other conversation than in comparing watches at the various stations. I got out of the carriage only once, at Rugby, I think, and for the last seventy or eighty miles the train did not stop. There was a clear moon the latter part of the journey, and the mist lay along the ground, looking very much like a surface of water. We reached London at about ten, and I found S——- expecting me.

Yesterday the children went with Fanny to the Zoological Gardens; and, after sending them off, S——- and I walked to Piccadilly, and there took a cab for Kensington Gardens. It was a delightful day,—the best of all weather, the real English good weather,—more like an Indian summer than anything else within my experience; a mellow sunshine, with great warmth in it,—a soft, balmy air, with a slight haze through it. If the sun made us a little too warm, we had but to go into the shade to be immediately refreshed. The light of these days is very exquisite, so gently bright, without any glare,—a veiled glow. In short, it is the kindliest mood of Nature, and almost enough to compensate for chill and dreary months. Moreover, there is more of such weather here than the English climate has ever had credit for.

Kensington Gardens form an eminently beautiful piece of artificial woodland and park scenery. The old palace of Kensington, now inhabited by the Duchess of Inverness, stands at one extremity; an edifice of no great mark, built of brick, covering much ground, and low in proportion to its extent. In front of it, at a considerable distance, there is a sheet of water; and in all directions there are vistas of wide paths among noble trees, standing in groves, or scattered in clumps; everything being laid out with free and generous spaces, so that you can see long streams of sunshine among the trees, and there is a pervading influence of quiet and remoteness. Tree does not interfere with tree; the art of man is seen conspiring with Nature, as if they had consulted together how to make a beautiful scene, and had taken ages of quiet thought and tender care to accomplish it. We strolled slowly along these paths, and sometimes deviated from them, to walk beneath the trees, many of the leaves of which lay beneath our feet, yellow and brown, and with a pleasant smell of vegetable decay. These were the leaves of chestnut-trees; the other trees (unless elms) have yet, hardly begun to shed their foliage, although you can discern a sober change of line in the woodland masses; and the trees individualize themselves by assuming each its own tint, though in a very modest way. If they could have undergone the change of an American autumn, it would have been like putting on a regal robe. Autumn often puts one on in America, but it is apt to be very ragged.

There were a good many well-dressed people scattered through the grounds,—young men and girls, husbands with their wives and children, nursery-maids and little babes playing about in the grass. Anybody might have entered the gardens, I suppose; but only well-dressed people were there not, of the upper classes, but shop-keepers, clerks, apprentices, and respectability of that sort. It is pleasant to think that the people have the freedom, and therefore the property, of parks like this, more beautiful and stately than a nobleman can keep to himself. The extent of Kensington Gardens, when reckoned together with Hyde Park, from which it is separated only by a fence of iron rods, is very great, comprising miles of greensward and woodland. The large artificial sheet of water, called the Serpentine River, lies chiefly in Hyde Park, but comes partly within the precincts of the gardens. It is entitled to honorable mention among the English lakes, being larger than some that are world-celebrated,—several miles long, and perhaps a stone's-throw across in the widest part. It forms the paradise of a great many ducks of various breeds, which are accustomed to be fed by visitors, and come flying from afar, touching the water with their wings, and quacking loudly when bread or cake is thrown to them. I bought a bun of a little hunchbacked man, who kept a refreshment-stall near the Serpentine, and bestowed it pied-meal on these ducks, as we loitered along the bank. We left the park by another gate, and walked homeward, till we came to Tyburnia, and saw the iron memorial which marks where the gallows used to stand. Thence we turned into Park Lane, then into Upper Grosvenor Street, and reached Hanover Square sooner than we expected.

In the evening I walked forth to Charing Cross, and thence along the Strand and Fleet Street, where I made no new discoveries, unless it were the Mitre Tavern. I mean to go into it some day. The streets were much thronged, and there seemed to be a good many young people,—lovers, it is to be hoped,—who had spent the day together, and were going innocently home. Perhaps so,—perhaps not.

September 25th.—Yesterday forenoon J——- and I walked out, with no very definite purpose; but, seeing a narrow passageway from the Strand down to the river, we went through it, and gained access to a steamboat, plying thence to London Bridge. The fare was a halfpenny apiece, and the boat almost too much crowded for standing-room. This part of the river presents the water-side of London in a rather pleasanter aspect than below London Bridge,—the Temple, with its garden, Somerset House,—and generally, a less tumble-down and neglected look about the buildings; although, after all, the metropolis does not see a very stately face in its mirror. I saw Alsatia betwixt the Temple and Blackfriar's Bridge. Its precincts looked very narrow, and not particularly distinguishable, at this day, from the portions of the city on either side of it. At London Bridge we got aboard of a Woolwich steamer, and went farther down the river, passing the Custom-House and the Tower, the only prominent objects rising out of the dreary range of shabbiness which stretches along close to the water's edge.

From this remote part of London we walked towards the heart of the city; and, as we went, matters seemed to civilize themselves by degrees, and the streets grew crowded with cabs, omnibuses, drays, and carts. We passed, I think, through Whitechapel, and, reaching St. Paul's, got into an omnibus, and drove to Regent Street, whence it was but a step or two home.

In the afternoon, at four o'clock, S——- and I went to call on the American Ambassador and Miss L———. The lady was not at home, but we went in to see Mr. ——— and were shown into a stately drawing-room, the furniture of which was sufficiently splendid, but rather the worse for wear,—being hired furniture, no doubt. The ambassador shortly appeared, looking venerable, as usual,—or rather more so than usual,—benign, and very pale. His deportment towards ladies is highly agreeable and prepossessing, and he paid very kind attention to S——-, thereby quite confirming her previous good feeling towards him. She thinks that he is much changed since she saw him last, at dinner, at our house,—more infirm, more aged, and with a singular depression in his manner. I, too, think that age has latterly come upon him with great rapidity. He said that Miss L——— was going home on the 6th of October, and that he himself had long purposed going, but had received despatches which obliged him to put off his departure. The President, he said, had just written, requesting him to remain till April, but this he was determined not to do. I rather think that he does really wish to return, and not for any ambitious views concerning the Presidency, but from an old man's natural desire to be at home, and among his own people.

S——- spoke to him about an order from the Lord Chamberlain for admission to view the two Houses of Parliament; and the ambassador drew from his pocket a colored silk handkerchief, and made a knot in it, in order to remind himself to ask the Lord Chamberlain. The homeliness of this little incident has a sort of propriety and keeping with much of Mr. ———'s manner, but I would rather not have him do so before English people. He arranged to send a close carriage for us to come and see him socially this evening. After leaving his house we drove round Hyde Park, and thence to Portland Place, where we left cards for Mrs. Russell Sturgis; thence into Regent's Park, thence home. U—— and J——- accompanied us throughout these drives, but remained in the carriage during our call on Mr. ———. In the evening I strolled out, and walked as far as St. Paul's,—never getting enough of the bustle of London, which may weary, but can never satisfy me. By night London looks wild and dreamy, and fills me with a sort of pleasant dread. It was a clear evening, with a bright English moon,—that is to say, what we Americans should call rather dim.

September 26th.—Yesterday, at eleven, I walked towards Westminster Abbey, and as I drew near the Abbey bells were clamorous for joy, chiming merrily, musically, and, obstreperously,—the most rejoicing sound that can be conceived; and we ought to have a chime of bells in every American town and village, were it only to keep alive the celebration of the Fourth of July. I conjectured that there might have been another victory over the Russians, that perhaps the northern side of Sebastopol had surrendered; but soon I saw the riddle that these merry bells were proclaiming. There were a great many private carriages, and a large concourse of loungers and spectators, near the door of the church that stands close under the eaves of the Abbey. Gentlemen and ladies, gayly dressed, were issuing forth, carriages driving away, and others drawing up to the door in their turn; and, in short, a marriage had just been celebrated in the church, and this was the wedding-party. The last time I was there, Westminster was flinging out its great voice of joy for a national triumph; now, for the happy union of two lovers. What a mighty sympathizer is this old Abbey!
